COMPOSITION OF MATTER FOR RESTORING THE PICTURES ON FILMS.

No Drawing.

T0 alt whom it may concern:

srnrrnn, a subject of the Emperor of Germany, and a resident of New York, county and State of New York, have invented a certain new and useful Composition of Matter for Restoring the Pictures 0n Films, of which the following is a full, clear, and exact specification.

This invention relates to a modified composition of matter disclosed in my pending applications for Letters Patent, Serial Number 732,465, filed November 20, 1912, Serial Number 770,177, filed May 27, 1913, Serial Number 771,689, fil ed June 45, 1913, Serial Number 774,864, filed June 20, 1913, and Serial Number 7 85,091, filed August 16', 1913.

My invention-has for its object primarily to provide a composition of 'matter designedto be employed for restoring the pictures of moving picture films when the texture of the film has become hardened, and the photographic pictures thereon have been impaired by scratches and the collection of particles of dust or other foreign substances after being transmitted a number of times through a projecting machine, the said composition being adapted to free the crevices of the scratches of all accumulated foreign matter as well as serving to clear the high lights and the shadows of the photography of the pictures, and also servingto soften the texture of'the film for restoring its flexibility. Thus moving picture films which usually become practically Worthless after being used a few times may be restored sufficiently so that the pictures thereof may be exhibited many times as occasion requires.

The composition of matter consists of the following ingredients, combined in the pro- Specification of Letters Patent.

Patented May 18, 1915.

' Application filed October 7, 1913. Serial No. 793,892.

, portions stated, viz ':a fatty base, such as lard, tallow, bees wax, paraflin, spermaceti,

petrolatum, or any suitable animal, vegetable, or mineral f at 6 ounces; alcohol (U. S. P. strength) by weight 2 ounces.

The alcohol is thoroughly incorporated in the fatty baseby any suitable means, and the composition is applied tothe surfaces of the moving picture film by the employment of a pad of chamois skin, orv other soft ma- "terial until a coating is formed thereon.

The coating on the film is then frictionally rubbed'by the use of the pad, or otherwise to soften the texture of the film for restoring its flexibility and until the crevices of the scratches have been thoroughly penetrated. By subsequently freeing the film of all surplus of the coating the foreign substances in the photography of the pictures and the foreign substances in'the scratches will be entirely removed so that the transparency of the film and the high lights and shadows of the pictures will be restored. In

this manner moving picture films which usually become" practically worthless after being useda few times may be restored sulficiently so that the pictures thereof may be exhibited many times.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A restorative for moving picture films comprising a fatty base six ounces, and alco-' hol two ounces, substantially as described. and for the purpose specified.

This specification signed and witnessed this sixth day of October A. D. 1913.
